The RAP will meet the requirements in N.C.G.S. Article 9- Part 8, 40 CFR 264.101 as adopted in l 5A NCAC 13A .0109, and the RCRA Permit and will protect future users and receptors at the site. The RAP is considered a Final Remedy and will be incorporated into the existing Resource Conservation and Recovery Act (RCRA) Permit through a Class 3 Modification. To accomplish this Permit Modification and as required by 40 CFR 270.42 as adopted in l 5A NCAC .0113 a modified Draft Permit has been prepared and is enclosed. Also enclosed are a Public Notice for the Draft Permit including the scheduling ofa Public Hearing and a Fact Sheet describing the Permit Modification.
